HandBrake is a video trans-coder developed upon Open Source coding, thus benefiting from the work of dedicated people worldwide. Most common input sources supported by this converter start from DVDs and end at Blu-Rays.
As for the output, we will mention MP4 and MKV. Options include a special tab for selecting the video encoder, the video quality, frame rate and audio pass.
Less important features but equally reliable integrate chapter selection and markers, support for subtitles and VFR and live video preview. For more advanced tweaking, users can take to the extensive list of available video built-in filters: Deinterlacing, Detelecine etc.
